DERAILER FOR RAILWAYS.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application led May 9, 1906. Serial No. 316,013.

To @ZZ whom it may concern:

Be it known that I, WILLIAM R. COCHRAN, Jr., a resident of Delphos, inthe county of Allen and State of Ohio, have invented certain new anduseful Improvements in Derailers for Railways; and I do hereby declarethe following to'be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it.appertains to make and vuse the same.

My invention relates to an improvement in derailers for railways, theobject of the invention being to provide improvements of this characterof extremely simple construction, cheap to manufacture, strong anddurable in use, and which absolutely prevents a train passing from asiding onto the main track when the maintrack is open.

A further object is toprovide improvements of this character whichpermit a train to pass onto the siding after the switchpoints arethrown, but automatically sets to prevent any return of the train untilthe switch is opened.

With these and other objects in view the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described, and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a plan view illustrating myimprovements. Fig. 2 is a view in section on the line a: thereof, andFigs. 3 and 4 are detail views.

1 represents the outside rail of a siding, and 2 my improved derailer,which is located some distance from the switch, as is customary.

The derailer comprises two main partsnamely, the derailer proper, 2,andits support or carrier 3. The support or carrier 3 has a smallplatform 4 and an outward extension 5. The platform 4 is secured to an:arm 6, which latter and an arm or extension 7 on the derailer arepivotally secured, as shown, permitting both to move vtogether or thederailer to move independently, as will hereinafter appear. The derailerrests on platform 4 and is recessed to receive the rail l and projectits top portion over the rail, forming a tread portion 8, onto which thewheel-tread rides, elevating the wheel-ange onto the derailer, thelatter being dished, as shown at 9,

to prevent the wheel-flange violently striking the same and permittingit to ride easily onto the derailer and move against a cam or diagonalfiange or web 10 on the derailer and be guided 'thereby off the rail.

The derailer is provided with a rod 11, secured thereto and movable in aperforated lug 12 at the outer end of extension 5, and a coiled spring13 is located on this rod between the lug 12 and the derailer tonormally hold the latter on platform 4, a lug 14 being provided onderailer 3 to compel the derailer to move back from the rail when theplatform 4 is moved.

A link 15 connects the arm 6 with the switch-throwing mechanism, (notshown,) so that when the switch is thrown the derailer will also bemoved, as will now be eX- plained.

The operation of my improvements is as follows: The derailer ismaintained in the position shown in Fig. 1 and is moved only when theswitch is thrown to open the siding. As the train passes from the maintrack onto the siding the switch is of course held open; but after thelast car has passed the switch the siding is closed when the last car issome distance from the derailer, and the latter will be moved over therail when the switch is thrown. l However, this will not interfere withthe rear end of the train passing onto the siding, as the wheel-flangeswill engage* the arm 7 and force the derailer back against the tensionof spring 13, which latter will return the derailer to normal positionover the rail. Any movement of the train toward the main track beforethe switch is open will cause the wheel-treads to ride on the treadportion 8 of the derailer, which will guide the wheel-fianges againstthe cam-web 1() and derail the car. It will thus be seen that while thewheels can pass the derailer when moving onto the siding even though theswitch be closed the wheels cannot pass to the main track until theswitch is open, and my improvements are an absolute preventative foraccidents due to this cause.

A great many slight changes might be made in the general form andarrangement of parts described without departing from my invention, andhence I would have it understood that I do not restrict myself to theprecise details set forth, but consider myself IOO l l l at liberty tomake such slight changes and alterations as Jfairly fall within thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination with a movable support, of a derailer movable on thesupport, means for moving the support to move the derailer away fromrail, and said derailer constructed to be moved independently of thesupport, by a wheel passing in one direction but derail the Wheel inpassing in the opposite direction.

2. The combination with a rail, of a derailer, an arm thereon pivotallysecured to one side of the rail permitting the derailer to be moved by awheel-flange engaging the arm, a tread portion on the derailer supportedon the rail7 a deflecting flange or web on the Vderailer to be engagedby a Wlieel-iange Awhen the wheel rides up on the tread and defleet thewheel from the track7 and a recess between the tread portion and iangeto permit the wheel-flange to ride onto the derailer Without violentlystriking the same.

3. The combination with a rail, of a platform, an extension thereon, apivoted arm secured to the platform, a derailer, an arm thereonpivotally secured to the pivotal end of the platform-arm7 a rod on thederailer movable in a lug on the extension, a spring on the rod bearingagainst the derailer, and a lug on the derailer to engage the platform.

4. The combination with a rail, a movable platform, means for connectingthe latform with a switch-throwing device to ook the platform againstmovement when the switch is thrown, of a derailer mounted to move on theplatform and constructed to be moved by the flange of a wheel in passingin one direction and to derail the wheel when passing in the reversedirection, and elastic devices normally holding the derailer over therail.

5. A derailer, having a pivoted arm made with a cam edge to be engagedby a wheellange to move the derailer out of the path of a wheel when theWheel is moving in one direction, a tread on the derailer supported onthe rail tol receive the wheel and elevate the lange of the wheel, and acam liange 0r web on the derailer to be engaged by the wheeliiange todeiiect the same from the rail.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
